Today, we went out of the house for about an hour and when we came back the whole kitchen was flooded. Turned out the cold water soft connection for the kitchen sink had somehow disconnected (?).
We have a finished basement underneath which was flooded too.
I immediately shut off the water and got rid of it but the question is whether I can do anything else to help the situation.
The floor is red oak and is not finished with polyurethane but with OSMO polyx oil (natural oil and wax). As far as I remember it has the subfloor underneath and that black tar paper or whatever it is on top of it below the hardwood floor.
There's sound insulation (ROXUL Safe'n'Sound) between the joists.
The dry wall everywhere (including the basement ceiling) is the green mold resistant drywall. The paint is Benjamine Moore Aura Bath & Spa.
The basement ceiling shows only slight signs of damage (you can now kinda tell where the sheets meet). The kitchen floor was OK initially but after a few hours the edges between the pieces of wood raised a bit and became black. Overall, the damages are minor and almost invisible.
What I worry about is that water is probably still trapped in the floor b/n the hardwood floor and the drywall below. I worry about developing mold and health issues more than the visible damages. What should I do?
